Question

can we see the atom? if yes how? how can we evident an atom?

Answer 1

Hi,
Your question-Can we see the atom?if yes how?how can we evident an atom?
Here's the answer------
So we can regularly see single atoms and atomic columns." That's because electron microscopes use a beam of electrons rather than photons, as you'd find in a regular light microscope. As electrons have a much shorter wavelength than photons, you can get much greater magnification and better resolution.
hope it helps

Answer 2

Yes, we can. 

So we can see atoms, but you're not really seeing the atoms, what you're seeing is the electron field created by the electrons around the atom and how they produce a current when they interact with a very fine tip on an electron microscope.

One more recent study imaged atoms in a slightly different way. What this study did was to take a sheet of graphene, a single layer of carbon atoms, rather like a honeycomb which stack up make graphite. If you peel away single layers of graphite you get graphene. And what this particular group in America did was to sprinkle some molecules onto this graphene sheet and then run a scanning tunnelling electron microscope across the surface. And because the graphene is so regular in structure, it's easy to mathematically subtract the effect of the graphene being there from any other signals that you get. This enables them to actually see the structure and shapes of molecules.
